The WorldChat example (https://github.com/graphcool-examples/react-graphql/blob/master/subscriptions-with-apollo-worldchat) exports

addGraphQLSubscriptions

from

subscriptions-transport-ws

, which will soon be deprecated: https://github.com/apollographql/subscriptions-transport-ws/issues/169. I see in the comments that https://github.com/scf4/add-graphql-subscriptions is an option, i.e.

import { addGraphQLSubscriptions } from 'add-graphql-subscriptions';

but now it’s throwing the following error:

wsClient.subscribe is not a function

.
